Current implementation causes test failures at video rendering to WebGL texture.

Looked into reftest failure of "no video copy". The failure might be specific to a NVIDIA GPU driver.

• At first, I thought the failure happened only WebGL video tests. It was wrong.
• The failures happened also just with video rendering test like short.mp4.lastframe.html

• texture array with shared handle might cause the failure. The failure might be specific to GPU driver.
• short.mp4.lastframe.html used virtualization: virtual-with-gpu (NVIDIA adapterDeviceID=0x13f2)
• "virtualization: hardware" used "Intel GPU adapterDeviceID=0x193a". It rendered short.mp4.lastframe.html correctly. But it had different reftest failures. I am going to look into them tomorrow.
• From the following, call sequence seemed to happen as expected.
